So you're saying if a file is a gzip/bzip/tar/cpio file, "file" will identify it as such, and not as an html file? That's exactly how I would expect it to work... >> To try to avoid these sloppy DNS servers I usually have Google's DNS servers >> 8.8.8.8 and 8.8.4.4 in my laptop's DNS settings.

Consider also the case of an organization wanting to offer a local private MacPorts distfiles mirror, for speed and to reduce their public bandwidth. They might do that by overriding the DNS result for distfiles.macports.org, redirecting it to a local caching proxy server. Making MacPorts always use a known-good DNS server would defeat that. >> The whole idea of many users globally using the same DNS servers -- Google >> DNS, OpenDNS, etc. -- is contrary to how DNS was intended to be used in the >> first place.

Indeed; I guess I'm mostly bemused that the original architecture of DNS has been turned on its head like this, and that it works so well. _______________________________________________ macports-dev mailing list [email protected] http://lists.macosforge.org/mailman/listinfo.cgi/macports-dev
